sounds like the wires you just repaired may be corroded.you might need to cut them back until you find good clean wire and replace a section.the wires to the tach sensor are up on the engine.not sure what your found by your battery.got a pic?
if the trans isn't having a problem,then the pcm must be getting a good clean signal,but your gauge isn't.

Just pull my 5th wheel that 38ft 3 slide wgt 16,500 lbs 250 miles back home to Fl. The truck did great i was able do 65 with it that foot to the floor
Ok i stop about 110 miles in to the trip to refuel and notice idle was up at about 800 to 850 where i started off at 650. so when was at fuel stop turn idle back down to 650 i haven't been out to day see what reading at
I'll also notice when had fuel to 3/4 to floor and then when mash on did see any change in power or rpm's i didn't see my rpm's go over 3000 rpm''s. Is there something on there it just seam like dead spot there thinking it could have pull little more speed out it
Went thur lot fuel haven't got mileage yet i know when stop put fuel front took 9gals and rear tank took 11 gals and drove other 74 miles and burn half tank on the rear

crazy you don't have many post here yet.i can't dig up any info on your truck.
so you just bought this old gal,and fixed up some leaky return lines.
though i do see in your garage some injectors.so you just changed these too?
so you have yourself;
94 F-350 CC turbo auto DRW 2x4 w/ 173k with........
a factory turbo probably being that she's a '94?
new injectors?
stock ip still?
boost or egt gauges yet?
fuel adjustment to the ip is likely still unknown right?
timing probably is unknown?
when you had her WOT pulling the 5ver at 65mph,did you notice any black smoke at all, at 3/4 to WOT?

yes factory turbo looks like mickey mouse exhaust system on it which needs to be fix
No the truck never put out any black smoke at all when pulling
now IP not sure if been replace or just work on it look like new sprigs, hight idle unit and tps looks new the IP is very clean not seeing any grey paint on it but know if they did when they came from factory
put new return lines on and only replace one injector that was cross threaded for as right now if decide keep the truck it will get new injectors , pump, 3in dp 4 in back with duel tails, air intake system and all the gauges
If i can get this truck pull at 75 mph i think would keep it. The one thing i can say it has lot more TQ then my 6.5 did

i think you'll find your going to be pleased once you do all that.
i forgot to ask which gears she has too.3.55's or 4.10's?
the axle code can be found on the drivers side door jam sticker if you haven't checked yet.
What rear end ratio is in my Ford , do I have positraction? - Drivetrain.com
you'll find with the new found power after the full tune up,and custom exhaust,that 75 is likely obtainable,but fuel economy will be much better towing that beast slower anyway (even if you had a new 6.7l sitting under the hood lol.)
another thing to consider,though im not sure what your budget is for the truck.but the weakest link to the E40D isn't the trans itself,but the stock converter.it's got a pretty high failure rate (unfortunately when they come flying apart,they clean out the whole trans with them.) the cure to this is swapping it out for a good built unit such as this:

Well old retired truck driver and doing 75 or 80 down the highway what been doing for yrs
If this works out right it will have it work out cause me and wife are full time Rv'ers and we put on 15,000 to 20,000 miles a yr and thing is i like old trucks better then new one don't like all that comptuer sh|t that they put in them

Thanks for that tip. Didn't know had weak converters in them
Thanks for the link the price may be high but it would cost hole lot more for new trans
Is there better auto trans out there that fit these motors ?
